@JasGot Awesome, thanks for the input. I'll look into SPF.
SPF is considered a requirement these days. And DKIM is heavily recommended.
People are starting to come around. I have been using DKIM for a few years for all services sending email outside our org. With O365, SPF and DKIM are part of the setup.
Same with Zoho.

Thanks. At this point, it is only companies that this request would apply to.

@pattonb said in DNS PTR Record with 2 FQDN Entries with SPAM Check:
@JaredBusch incorrect, Scott has summarized succinctly
That is what you asked. But going with that is not what you actually wanted, then the answer to your original post is that you don't fix anything.
You whitelist the domain in question and move on.
The sender's ISP is in charge of setting the PTR record and there is not a damned thing you can do about it.

@scottalanmiller said in Sales Person Wants Me to Provide Independent Rep With an Email Account:
My second thought is, if having an email account creates a security concern, it is not creating the account that creates the problem, it simply exposes an existing security problem.
Not necessarily security, but accessing features like SFB, OD and Teams. But, as Kelly mentioned, they have Exchange Online P1, which doesn't have any of the other services (different than E1.)
Right, i was assuming that they'd only get email. Even those other things, though, still have security. but no reason to think that you'd provision those, too.

@dbeato said in Office 365 User Quarantine - How Do You Access After Redesign?:
@wrx7m I have not found a way to do so, you can create a folder in Outlook to manage it from there. Example here
http://www.expta.com/2015/02/how-to-add-access-to-office-365-eop.html
Have you done this? The link that includes admin seems like it would try to access the admin portion, not the specific user's quarantine. If this works as I need, I wonder if there is a policy to set this up, or if it would be a manual, one-by-one endeavor.
I have not but I can test.

I have been running Mailcow for a little while, been testing and playing about with it. I'm quite impressed how it's all been put together. I would love to hear how many mailboxes people are running this in production.
Not using a reverse proxy on mine though.

@Dashrender said in Email server options:
This comparison misses taking it beyond year 5.
Why take it beyond 5 years? Because if it is on premises, it will need to be upgraded again.
@Dashrender said in Email server options:
If you add SA to the original licenses - because you know the plan is the keep using Exchange going forward - it will raise the costs noticeably in the beginning, but come renewal time it will make it significantly less. Less enough to be under O365? not likely, hell, even the 5 year plan would be more expensive for onprem vs O365... but it might lower itself over time because of the SA difference.
SA is a scam to get more money. Always has been for the SMB. With negotiated pricing for Enterprise, it is the right thing.
If you're a company that only upgrades once every 10 years - then yeah... SA is a waste of money, but you're already talking about upgrading again in 5 years, so SA could very much make financial sense - show me the numbers before you poo poo it.

@zachary715 said in Does Anyone Actually Use Conversation View Intentionally for Email:
All of my folders are subfolders of my Inbox, so although my Inbox itself is kept clean, I can easily search my Inbox and it searches the entirety of all subfolders. CV doesn't make this any more or less complicated.
Me, too. But every system handles broken up threads like that differently.

https://tools.ietf.org/html/rfc5322#section-3.6.2
Originator Fields
The originator fields of a message consist of the from field, the
sender field (when applicable), and optionally the reply-to field.
The from field consists of the field name "From" and a comma-
separated list of one or more mailbox specifications. If the from
field contains more than one mailbox specification in the mailbox-
list, then the sender field, containing the field name "Sender" and a
single mailbox specification, MUST appear in the message. In either
case, an optional reply-to field MAY also be included, which contains
the field name "Reply-To" and a comma-separated list of one or more
addresses.
from = "From:" mailbox-list CRLF
sender = "Sender:" mailbox CRLF
reply-to = "Reply-To:" address-list CRLF
The originator fields indicate the mailbox(es) of the source of the
message. The "From:" field specifies the author(s) of the message,
that is, the mailbox(es) of the person(s) or system(s) responsible
for the writing of the message. The "Sender:" field specifies the
mailbox of the agent responsible for the actual transmission of the
message. For example, if a secretary were to send a message for
another person, the mailbox of the secretary would appear in the
"Sender:" field and the mailbox of the actual author would appear in
the "From:" field. If the originator of the message can be indicated by a single mailbox and the author and transmitter are identical, the "Sender:" field SHOULD NOT be used. Otherwise, both fields SHOULD appear.
Note: The transmitter information is always present. The absence
of the "Sender:" field is sometimes mistakenly taken to mean that
the agent responsible for transmission of the message has not been
specified. This absence merely means that the transmitter is
identical to the author and is therefore not redundantly placed
into the "Sender:" field.
The originator fields also provide the information required when
replying to a message. When the "Reply-To:" field is present, it
indicates the address(es) to which the author of the message suggests
that replies be sent. In the absence of the "Reply-To:" field,
replies SHOULD by default be sent to the mailbox(es) specified in the
"From:" field unless otherwise specified by the person composing the
reply.
In all cases, the "From:" field SHOULD NOT contain any mailbox that
does not belong to the author(s) of the message. See also section
3.6.3 for more information on forming the destination addresses for a
reply.

e got a strange one... I have a user here whose Emails go from whatever folder they are in to the Deleted Items folder after being read... Sometimes. Sometimes it doesn't happen for several minutes, and other times it happens right away.
The user hasn't been phished that we can tell. No bogus rules in Outlook forwarding things to the deleted items. Check both Web and Outlook 2016.
What am I not looking at that could be causing this?
They got hacked though

https://docs.microsoft.com/en-us/office365/securitycompliance/responding-to-a-compromised-email-account
Sometimes the rule is a dot on the name....
I am assuming it's a hacked account, but we changed the password to a new one. I disconnected all of her sessions from Office 365.
Still happening. I see no rules with a dot in the name... or spaces or foreign characters. I see exactly the number of rules on my CLI as I do in Outlook and OWA.
Can you clear them all ? Take a screenshot of the settings and then remove them and see what changes. The rules run autonomously and is not someone running them.
That's what we've done now. All of the rules are disabled. End-user is turning them back on one at a time now.

@LilAng said in Copy / Paste from Excel on Mac to Outlook Web Access Creates Image Rather than Table:
In Excel, use File > Save as web page, then attach the web page to your email message?
Yeah, we found that process. That's a pretty huge "fail" process.

I have a script that I wrote to do this.
https://gitlab.com/dafyre/powershell-utils/raw/master/export-O365Group.ps1
It gets you the person's DisplayName and their email address.
If you're exporting a Distribution List, just add the -distributionlist switch.
If you're exporting an Office 365 Group (Unified Group), then leave that switch out. Other parameters should be self explanatory.

Depends how it is done. It's online, not offline. But it can be airgapped.

Hmmm I just upgraded from 8.8.9 to 8.8.11 last week or two weeks ago.
